Abstract
The utility model relates to a bicycle capable of regulating posture, composed of a frame, a front wheel, a back wheel, a saddle, a handle, a chain, chain wheels, pedals and a saddle supporting beam. The utility model is characterized in that the of the saddle (1) is connected with the upper end of the saddle supporting beam (3) by a shaft (2), the lower end of the saddle supporting beam is connected with a lower beam of the frame by a shaft (8), and the saddle supporting beam moves along an upper beam around the shaft (8) and is fixed by a locking mechanism. When on the uphill road, the saddle is regulated frontward and upward and then is locked. When on the downhill road, the saddle is regulated backward and downward and then is locked. When on the level road, the position of the saddle can be optionally regulated, in order to change the posture and relieve the fatigue. The double-vertical beam structure is helpful to ensure that the direction of the saddle is not changed after the posture is regulated.
Description
Adjustable attitude bicycle belongs to the vehicle.
After bicycle is set up the vehicle seat height according to car user's stature condition now, vehicle seat, handlebar, axis relative position are fixed in the process of riding, the car user can't adjust attitude, there is following shortcoming in this kind structure: in the process of riding of 1, going up a slope position of human center backward, move down, horizontal direction is away from axis, make to step deleterious, and make the people very easily tired.2, descending is ridden in the process, the gravity center of human body forward, move up, the steering stability of bicycle is reduced, and the trailing wheel load is reduced and cause the trailing wheel braking effect to reduce, this point especially retains under the situation of ice and snow influence greatly to the north of china in winter road surface, because this situation front wheel brake very easily slips, during trailing wheel braking effect difference, braking performance of vehicle greatly reduces.3, during long-distance riding, with keeping a kind of attitude, the part muscle group was in tension for a long time when human body was long, and is very easily tired.With common 26 inches bicycles is example: go up a slope 5 ° the time, gravity center of human body's (intending being the vehicle seat center) is with respect to the mobile backward 78mm in front and back wheel touchdown point center, move down 23mm, and during 5 ° of descendings, the gravity center of human body is with respect to moving 16.5mm on the front and back wheel touchdown point center, reach 78mm.
The utility model is in view of the above-mentioned shortcoming of standard bicycle, provides a kind of human body attitude of adjusting in the process of riding to adapt to the uphill/downhill road and long-distance riding slowed down the bicycle of tired needs.
The purpose of this utility model is achieved in that the vehicle seat bottom is connected in vehicle seat support beam upper end by axle, and vehicle seat support beam lower end is connected on the lower frame rail by axle.The vehicle seat support beam can be around axle along putting the beams in place mobile and being fixed by lockout mechanism.Change the structure of traditional fixedly vehicle seat support beam supporting seat into moveable cart seat supports beam supporting seat.In order to prevent that vehicle seat from bending forward and backward, can adopt two vehicle seat support beam structures, be fixed with lockplate on the front seat support beam, the lockplate front end is hung extension spring, and the extension spring other end is hung on the upper beam appropriate location.Latch hook is equipped with in upper beam corresponding position, lockplate top, handles and mentions arbitrarily or put down latch hook and pin lockplate in select location by being connected to backguy on the handlebar, realizes that not Parking condition downward modulation car load seat puts with the adjustment attitude of riding.Like this, when riding in uphill way, adjusting vehicle seat makes it forward, the back locking is moved in the top, can offset the adverse effect that vehicle seat is moved down backward because of upward slope, obtain the required bigger driving effect that steps when going up a slope, and when descending is ridden, adjustable car load seat make its backward downward direction move counteracting and make vehicle seat forward because of descending, the adverse effect that move the top, during long-distance riding, a kind of attitude time is grown the people is felt fatigue, at this moment adjustable car load seat is put to change attitude, the original higher muscle group of tensity is loosened and has a rest, to slow down fatigue.
Great advantage of the present utility model is: 1, can adjust attitude to adapt to or downhill path and slow down tired needs.2, can carry out when driving.3, the vehicle seat direction is constant before and after keeping adjusting.
Concrete structure of the present utility model is provided by following examples and accompanying drawing.
Accompanying drawing is the structural representation according to the adjustable attitude bicycle that the utility model proposes.
Describe in detail according to specific structural details and the service condition that the utility model proposes below in conjunction with accompanying drawing.
Wheel of the present utility model, handlebar, chain, sprocket wheel, turn greatly, pedal is identical with existing bicycle.Vehicle frame (10) can be fixed two axles (8), the upper end can guarantee that two vehicle seat support beams (3) move freely two vehicle seat support beams (3) lower end existing together of two bifurcated beams and are connected on the underbeam by axle (8), and can connect vehicle seat (1) by axle (2) on axle (8) rotates.Lockout mechanism is made up of lockplate (6) and latch hook (4), lockplate (6) is contained on the vehicle seat support beam (3), latch hook (4) is contained in the corresponding position of upper beam, extension spring (7) one ends are hung on the lockplate (6), in addition end is hung on the upper beam, and it is liftable or put down latch hook (4) by backguy (5) that operating handle (9) is housed on handlebar.
In the process of riding, bar handle (9) lifts latch hook (4) by backguy (5), and centre of body weight is shifted to pedal, and vehicle seat support beam (3) rotates around axle (8) under the drive of extension spring (7), drives vehicle seat (1) and is adjacent to health.Can make this moment health continue reach, vehicle seat is adjacent to health to front position more, and bar handle (9) puts down latch hook (4) and pins lockplate (6), and vehicle seat is fixed in more preceding position, rides or adjusts the attitude needs to adapt to go up a slope.But also move behind the health promote vehicle seat (1) backward, after the below moves, locking system is to adapt to descending or to adjust the attitude needs.Owing to adopt the structure of two vehicle seat support beams (3), adjusting the attitude front and back, vehicle seat (1) can keep horizontal direction substantially.
Claims (2)
1, adjustable attitude bicycle, form by vehicle frame, front-wheel, trailing wheel, vehicle seat, handlebar and chain, sprocket wheel, pedal, vehicle seat support beam, it is characterized in that: vehicle seat (1) bottom is connected in vehicle seat support beam (3) upper end by axle (2), vehicle seat support beam lower end is connected on the lower frame rail by axletree (8), vehicle seat support beam (3) can be around axle (8) along put the beams in place moving with the adjustment attitude of riding, and fixed by lockout mechanism.
2, by the described adjustable attitude bicycle of claim 1, it is characterized in that said lockout mechanism is made up of lockplate (6) and latch hook (4), lockplate (6) is contained on the vehicle seat support beam (3), latch hook (4) is contained in the corresponding position of upper beam, extension spring (7) one ends are hung on the lockplate (6), and the other end is hung on the upper beam (10).
